2010 BMW Z4 Owners Manual – Editors are aware: This assessment was written in August 2009 concerning the 2009 BMW Z4. Little substance has been modified with this yr’s mannequin. To see what’s new for 2010, click on right here, or take a look at side-by-side comparability of the two mannequin years.

Information experiences recommend that prosperous automobile buyers are laying aside new purchases, retaining their present wheels, and treading water as they await the economic system to choose again. For those who’re on this group, BMW’s redesigned Z4 isn’t your most accountable choice, but when instances had been good, you’d snap it up in a heartbeat. It’s an agile, sharp-looking roadster with a respectable cabin house and surprisingly comfortable journey high quality for day-to-day use. So be an optimist: The brand new Z4’s timing could also be lower than best. However, it’s too good a specimen not to contemplate.

I examined a Z4 sDrive35i. There’s additionally a much less highly effective Z4 sDrive30i; you possibly can evaluate each to the 2008 Z4 right here. This yr’s Z4 will get a regular power-retractable hardtop, very like BMW’s Three Collection convertible. Meaning there’s no fixed-hardtop coupe because the outgoing Z4 lineup is included; neither is there a high-performance Z4 M, additionally supplied beforehand.

Sharp Styling

The earlier Z4, conceived throughout the worst of BMW’s avant-garde styling years, at all times appeared a bit off. It was the form of an automobile you’d park nose-in so others may admire the rear and by no means see the entrance. There’s no want to cover anymore. The low-slung Z4 appears to be well-proportioned and aggressive, with an extended hood, a short tail, and a cabin planted rear of the automobile’s heart. The grille is bigger and extra upright, and the headlights have a furrowed, menacing look. It’s an angrier look. However, I’ll take it over the earlier Z4’s headlights, which lent the automobile a vapid expression.

The sDrive35i provides titanium-colored inserts within the grille and decreases air dam; the sDrive30i retains black inserts all through. BMW says the ability prime takes about 20 seconds to boost and decrease; I hit that point, decreasing it, however placing it up took 22 seconds. The entire operation requires the automobile to be at an entire halt; some powered tops perform when the automobile is in movement, not less than as much as a sure velocity.

Twin-Turbo Fun

The Z4 sDrive35i is probably the very best software but for BMW’s twin-turbo six-cylinder. Energy is plentiful, beginning out sturdy — and missing any noticeable turbo lag — and sticking round all the best way to a dashing ticket. Sports activities vehicles from the Nissan 370Z to the Porsche Boxster S feel much less instantly highly effective, peaking solely because the tach swings previous 3,000 rpm or so. BMW says 60 mph is available in 5.1 seconds for the Z4 sDrive35i. That’s a determine each rival narrowly beat, however within the regularly since the Z4’s steadiness of energy everywhere in the tach makes up for the deficit.

Different Bimmers supply the identical twin-turbo engine because the Z4 — and speed up as blazingly quick — however, the Z4’s stick is a welcome change from the rubbery, longish shifters BMW installs elsewhere. It feels nearer to the guide within the Infiniti G37, which I consider is the gold commonplace for stick-shift precision. Flick it from one gear to the following, stab the gasoline for a fast rev-match, then speed up onward — it’s a pleasant factor, and that does not praise I’ve paid a BMW guide in a very long time.

A seven-speed dual-clutch automated with steering-wheel paddle shifters runs $1,525 on the sDrive35i; the sDrive30i presents a conventional six-speed automated. The Z4’s dual-clutch transmission debuted within the M3 a pair of years again, and it was BMW’s first such transmission. Due to lickety-split shift instances, the dual-clutch automated will get the Z4 to 60 mph a hair sooner than the stick shift. (That is the norm for dual-clutch automatics, an actuality that I, a stick-shift purist, have solely grudgingly accepted.)

All-disc antilock brakes carry the Z4 to a fast halt, although I saw that the primary few inches of pedal journey precise minimal braking. Different editors discovered that helped fine-tune deceleration; however, I desire the Boxster’s brake pedal, which felt extra linear.

If the 300-horsepower sDrive35i’s $51,650 asking worth is simply too steep, the usually aspirated, 255-hp sDrive30i begins at $45,750. It hits 60 mph in 5.6 seconds with the guide and 6.zero seconds with the automated — probably a noticeable sufficient distinction from the twin-turbo engine so that you can feel in regular driving, particularly when evaluating the automatics.

Dynamic Drive Control

BMW’s Dynamic Drive Management, which impacts the steering feel, accelerator sensitivity, and stability system thresholds, is commonplace. My check automobile got here with a $2,300 Sport Bundle with an adaptive suspension, whose settings DDC additionally governs. DDC might be moved using Regular, Sport, and Sport Plus modes through a rocker change after the gearshift — an eminently helpful setup, I’d add, since you don’t should futz with an onboard laptop or set unbiased driving and suspension settings, as another vehicle with selectable driving settings require.

Ride & Handling

In DDC’s Regular mode, the Z4 is surprisingly docile: The steering wheel turns with an unexpectedly gentle contact, and the suspension soaks up bumps properly. As compared, the Boxster’s steering takes on a heavier feel, and high journey quality is much much less forgiving. Mercedes’ SLK350 has a good cushier journey however suffers from numb, dispirited steering. It isn’t fairly as straightforward to rotate the automobile on its axis within the BMW and slide the tail sideways as it’s within the Boxster, however for those who’re not a racetrack fanatic, I believe the ride-quality payoff will likely be definitely worth the loss.

Swap DDC to Sport and the Z4’s steering wheel feels heftier; it requires extra muscle to crank at low speeds however delivers sharper precision and a planted, safer freeway feels. It’s simpler in fast corners to sense the rear popping out and to ease off the gasoline or counter-steer as wanted. By comparability, the regular mode has a bit of an excessive steering slop to handle clear drifts.

The adaptive suspension will get firmer in Sport, although not intolerably so. Of larger import is physique roll: In Regular mode, fast lane adjustments unleash loads of physique roll. In Sport, the automobile stays a lot flatter.

Sport Plus mode eases again the Z4’s commonplace digital stability system so you possibly can spin the tires and let the tail break away a bit extra. In Regular or Sport, the steadiness system allowed sufficient wheelspin for me, and I didn’t discover another nice distinction from the opposite settings — steering help, suspension firmness — in Sport Plus. It’s not as apparent because of the transition from Regular to Sport, anyway. Sport Plus may come in useful on the racetrack; it serves much less goal on the road.

Energy the highest up, and wind noise is impressively quiet — one of many advantages of a hard- moderately than a soft-top convertible.

The Inside

If the earlier Z4 had a significant shortcoming past its controversial styling, it was a cramped house. The brand new Z4 is appreciably roomier — the seats don’t constrict your sides, and there’s a good quantity of legroom while you transfer them again. I’m 5-foot-11, and even once I received the seat into an excellent place to work the clutch, it was nonetheless just a few inches ahead of its rearmost place. With the automated, you possibly can most likely sit farther again, and there’s room to spare for that.

Your passenger will lament the lack of knee room. However, this cupholder is far superior to the earlier flip-out dashboard one. Inform him the choice could be to have espresso in his lap when that flimsy machine failed.

I’m not bought on the assortment of local weather controls — their look doesn’t match the remainder of the cabin’s styling — nor do I just like the Z4’s dash-top bin, whose tinny cowl smacks of cost-cutting. Go for the navigation system, and its display screen goes there as an alternative. You’ll also get BMW’s knob-based iDrive system, whose newest era is so huge an enhancement over its uniqueness that it most likely deserves a unique identity.

Cargo quantity measures a helpful 10.9 cubic ft with the highest up; put the highest down, and it drops to six-four cubic ft. The Boxster, SLK, and Audi TT have a comparable house with the highest up. However, all three have less-obstructed confines with the highest down; the Boxster’s and TT’s cargo areas are unaffected by their tops’ location.

Safety, Features & Pricing

The Insurance coverage Institute for Freeway Security has but to check the Z4; IIHS doesn’t crash-test many roadsters — and no previous Z4 has been examined — so I wouldn’t maintain my breath. Normal security options embrace antilock brakes, an digital stability system, standard entrance and knee airbags, and side-impact airbags that stretch excessively sufficient for head safety in response to BMW. Click on right here to see the complete listing of security gear.

The Z4 sDrive30i, which begins at $45,750, consists of the usual power-retracting hardtop, 17-inch alloy wheels, xenon headlights, vinyl upholstery, and a CD stereo with an MP3 jack. Leather-based upholstery and dual-zone automated local weather management are among the many choices. Each is commonplace on the Z4 sDrive35i ($51,650); additional choices on each fashion embrace energy seats, a premium stereo with an iPod/USB port, heated seats, a heated steering wheel, and a navigation system. The six-speed automated runs $1,325 on the sDrive30i; the seven-speed dual-clutch automated is $1,525 on the sDrive35i.

Z4 in the Market

BMW is a model that emphasizes efficiency, typically above all else, and the earlier Z4 took that too far. Quick however flawed, it had too many compromises for broad attraction. On the entire, Luxurious roadsters may have restricted success till the economic system beneficial properties some steam; however, the brand new Z4 will get a variety of issues proper. When luxury-car buyers return to purchasing weekend toys, BMW has one thing that must do the trick. And it’d simply suffice for weekdays, too.
